Bluetooth AND USB support?


Uwe Fechner
 

Hello,

I am looking for a chip/ board that has Bluetooth AND USB which is supported by Zephyr.

For example, the STM32WB55RG offers USB and Bluetooth, but it looks as if Zephyr does NOT support the USB part yet.

See: https://docs.zephyrproject.org/latest/boards/arm/nucleo_wb55rg/doc/nucleo_wb55rg.html

Is my impression correct?

Would it be difficult/ time consuming to make USB work?

Is there any other chip/board where Zephyr supports both?

Uwe

Hi Uwe,

The nRF52840 and the nRF5340 ICs from Nordic support both USB and Bluetooth.
There are several boards based on those supported by Zephyr.

Hi Uwe,

Looking at the board device tree description, USB is actually supported on this board:

&usb {
status = "okay";
pinctrl-0 = <&usb_dm_pa11 &usb_dp_pa12>;
};

I'll update the doc to reflect this state.
